1. Why does Alcoa want to combine with Alcan?

The transaction will create a premier diversified global aluminum company, with a complementary portfolio of assets and enhanced growth opportunities. The global landscape of the aluminum industry has changed in the last decade, and continues to change dramatically. The combination of Alcoa and Alcan will create a stronger, more diverse global competitor with the scale necessary to enhance our competitiveness in an evolving industry landscape. Together, Alcoa and Alcan will be better able to compete and win in an industry where our competitors in China, Russia and elsewhere are expanding. Alcoa and Alcan bring together a complementary portfolio of businesses and will benefit from a broader talent base and shared values. The combined company will have a better balance of growth projects, and be better able to prioritize and execute upon these opportunities. The combined company also will have increased financial resources to fund growth and research and development, while better managing risk. We believe this merger will create tremendous benefits for all our stakeholders - employees, customers, shareholders and the communities in which both companies operate.


2. Why is Alcoa launching an offer to purchase Alcan rather than try to reach a negotiated transaction?

Alcoa diligently tried to negotiate a transaction with Alcan for almost two years. We are very disappointed that our conversations with Alcan did not result in a negotiated transaction. Alcoa would have strongly preferred to negotiate an agreed transaction with the support of the Alcan Board of Directors; however, we have exhausted all options other than a direct offer to Alcan shareholders and believe the time is right to move forward.


3. What are the terms of the offer?

Alcoa will be making an offer to acquire all of the outstanding common shares of Alcan for US$58.60 in cash and 0.4108 of a share of Alcoa common stock for each outstanding common share of Alcan. Based on Alcoa’s closing stock price on May 4, 2007, the offer has a value of US$73.25 per Alcan share or approximately US$33 billion in enterprise value. The Alcoa offer represents a 32% premium to Alcan’s average closing price on the NYSE over the last 30 days and a 20% premium to Alcan’s closing price on May 4, 2007. Alcoa expects to formally commence its offer on Tuesday, May 8, 2007.


4. Does the offer require shareholder approval?

The proposed combination would require shareholder support from Alcan’s shareholders in the form of tendering their shares into the offer. Alcoa shareholder approval is not required.


5. What percent of Alcan shares will need to be tendered to meet the minimum condition to complete the transaction?

66 2/3% of Alcan’s outstanding common shares tendered.


6. Can shareholders elect all cash or all stock?

No. The mix of consideration is fixed.

What kind of regulatory approval will this transaction require? Do you believe you will be required to make any divestitures in order to gain regulatory approval?

The proposed combination is subject to customary conditions including regulatory approvals from competition authorities in various jurisdictions including the U.S., Canada, the European Union, Australia and Brazil. It also requires foreign investment clearance in Canada, France and Australia.



We have carefully considered the antitrust issues and are confident that the transaction will be approved. We have approached regulators in certain jurisdictions and are prepared to make the necessary targeted divestitures in particular industry segments. We believe any necessary divestitures will be focused and will not impair the value of the transaction.


7. How will this transaction impact Canada?

Alcoa is committed to growing the combined company’s already substantial presence in Canada, particularly in Québec and British Columbia. Alcoa generated more than $3 billion of total revenues last year through its operations in Canada and employs over 5,000 people there. Alcoa’s desire to expand our existing Canadian operations is a matter of public record and the combination of the two companies will make this goal a reality.

The new company will have dual head offices in Montreal and New York – with strategic management functions located in each city. Montreal will also become the combined company’s global headquarters for primary products (bauxite, energy, alumina and aluminum), as well as for related research and development. As a stand-alone company, the primary products business would be the largest aluminum company in the world and larger than Alcan is today with $32 billion in 2006 revenues and approximately 38,000 employees in 29 countries around the world, ranking among the largest businesses in Canada.

Alcoa also intends to promote new investment and greater opportunities for growth of the combined business through the responsible development of Canada’s industrial base. In particular, Alcoa expects to conclude negotiations with the government of Québec that will allow it to implement the companies’ planned investments of approximately US$5 billion, including modernizations and expansions, making it the single largest private sector investment program in Québec’s history. In British Columbia, Alcoa is committed to working with the government of British Columbia and local communities and First Nations to move forward with Alcan’s planned modernization of the Kitimat smelter.

Alcoa will honor Alcan’s commitments to the governments of Québec and British Columbia and the combined company will continue to pursue excellence in environmental, safety, health and technology leadership – areas in which both our companies have achieved international and local recognition. In addition, Alcan and Alcoa have a strong tradition of commitment to local communities and we will continue that tradition as a combined company.


8. What is the size of a combined Alcoa-Alcan?

On an aggregate basis for 2006, the combined company would have had revenues of US$54 billion and EBITDA of US$9.5 billion before synergies. In 2006, the combined company’s alumina production capacity would have been 21.5 million tonnes, and it would have had primary aluminum capacity of 7.8 million tonnes. In addition, the combined company would have approximately 188,000 employees in 67 countries.


9. Will this combination be more exposed to cyclical economic changes and metals prices?

This transaction makes strategic sense and is financially compelling under a range of potential metal prices. Many of the advantages to this transaction – such as value creation from integration, application of operational best practices and a lower cost base – are largely independent of metal prices. We are positive on aluminum market fundamentals, and we believe that the combined company will uniquely benefit from positive long term trends in the aluminum market. With our size and scale, we are confident in our ability to weather cyclicality in metal prices.



10. When is this transaction expected to be accretive?

We expect that the proposed transaction will be accretive to both EPS and cash flow per share within the first year of operations as a combined company.


11. What synergies do you expect from the transaction?

We expect annual savings of approximately US$1 billion from cost synergies alone. Key areas of cost savings include operational improvements in the areas of smelting, refining and R&D, procurement and packaging, and overhead improvements, such as SG&A and plant costs. The synergies will be phased in over three years with 100% fully achieved by the end of the third year after closing. We believe that these are very realistic and achievable synergy estimates, consistent with our prior deals and other deals in the sector.


12. Who will run the new company?

It is too early to discuss specifics. However, Alcan management has done an excellent job managing their company and the new company will draw the best talent of both existing organizations for key management position. Alcoa has a successful track record of integrating top talent from mergers and acquisitions.


13. What will the new company be called?

While this decision has not yet been made, we intend to preserve the heritage of the Alcan name and brand.


14. Will any employees be laid off as a result of this transaction?

While it is still too early in the process to discuss specifics, we do expect there to be some redundancies related to reducing corporate overheard. However, there are also substantial opportunities for growth resulting from this transaction. We are committed to staffing the new company with the best talent of both organizations.


15. Where will the combined company be traded?

We have applied to list the Alcoa common shares on the TSX, in addition to maintaining its listing on the NYSE, and Australian and UK exchanges and other foreign exchanges on which we trade today.


16. What is your estimate of when the deal will close?

We are targeting completion of the acquisition by the end of 2007. In the meantime, we will continue to post information about our offer here on our website,
